We have to see what happens with Iniesta for Barcelona because the midfielder had a little tear. But if he is able to train with the team properly before the Chelsea game, Ernesto Valverde may consider him, even though he's been out since sustaining the injury.

Iniesta has recovered much earlier than expected, but this is the sort of game he is understandably willing to risk his fitness for. After all, for Barcelona to adopt their preferred style of play, Iniesta has to feature.

Having said that, at Stamford Bridge, Chelsea were superior. I spoke to a few Chelsea players after the game and they came to the same conclusion - a better result escaped them.

In terms of their squad, this is the worst Barcelona in 10 years. That means Barca will always give you a chance.

Barcelona will look to star man Lionel Messi to overcome Chelsea this season

But Chelsea will have to be clinical, more than they were at Stamford Bridge, to take the two or three chances that come their way in order to progress, because Barca will create more than they did in London.

Lionel Messi is growing as player, not just as a goalscorer, and he understands what is required in every part of the pitch and every stage of the game.

The Argentina international has appeared when he is needed this season, especially in the big games, so the Catalans have a strong chance of progressing. However, Chelsea will have their moments, and it remains to be seen whether they take it.
